1 Claim.

The present invention relates to new and useful improvements in pumps and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character which is particularly adapted for dispensing liquids from barrels and other containers.

Another very important object of the invention is to provide a pump of the aforementioned character embodying novel means through the medium of which said pump may be adjustab'ly mounted in the barrel or other container.

Still another very important object of the invention is to provide a pump of the character described embodying novel locking means for preventing unauthorized operation of said pump.

Other objects of the invention are to provide a pump of the character set forth which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure l is a view in side elevation of a pump constructed in accordance with the present invention.

Figure 2 is a view in rear elevation thereof.

Figure 3 is a View in vertical section through the upper portion of the pump, taken substantially on the line 33 of Figure 2.

Figure 4 is a detail view in elevation of the valved piston.

Figure 5 is a detail view in vertical section through the valved piston, taken substantially on the line 55 of Figure 4.

Figure 6 is a detail view in vertical section through the foot valve.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises an elongated, tubular barrel I which may be of any suitable metal. Mounted for vertical sliding adjustment on the barrel I is a metallic sleeve 2 l'iavin a split, externally threaded lower end portion 3. Threaded on the lower end portion 3 of the sleeve 2 is a nut 4 which is adapted to contract said sleeve in a manner to clamp and frictionally secure same in adjusted position on the barrel I. The threaded lower end portion 3 of the sleeve 2 is also adapted to be screwed into the usual bung or opening 5 of a barrel or other container 6. Handles I project from diametrically opposite sides of the upper portion of the sleeve 2.

Operable in the barrel I is a manually actuated rod 8. The rod 8 extends above the upper end 5 of the barrel I and is provided with an annular handle 9 on its upper end. On the lower end of the rod 8 is a valved liquid elevating piston I0. As best seen in Figures 4 and 5 of the drawings, the lower end portion of the rod 8 is split or 10 bifurcated, as at II, and is provided with a cylindrical cage I2. Threaded into the lower end portion of the cage I2 is a seat I3. A ball check valve I4 is operable in the cage I2 and engageable on the seat I3.

In the lower end portion of the barrel I is a foot valve I5. The foot valve I5 comprises a seat It threaded into the lower end portion of the barrel I and provided with diametrically opposite notches or slots H in its lower end portion for receiving a screw driver or other suitable tool. The slots I'I also permit entrance of the fluid should the pump be engaged directly with the bottom of the barrel. A ball check valve I8 is engageable with the seat It. In the lower portion of the barrel I is a cross pin I9 for limiting upward movement of the valve I8.

The rod 8 extends slidably through a substantially cup-shaped bushing 2'0 (see Fig. 3) which is threadedly mounted in the upper portion of the barrel I. Thr-eadedly mounted on the bushing 29 is a packing nut 2|. The nut 2| is provided with a comparatively large opening 22 which accommodates the rod 3. This opening 22 is sealed by a washer 23 through which the rod 8 is slidiable. The reference numeral 24 designates a packing of suitable material in the nut 2| which prevents leakage around the vertically reciprocating rod 8.

Projecting from the upper portion of the barrel I is an inclined spout 25. The reference numeral 26 designates a flexible extension on the spout 25. Fixed on the spout 25, adjacent the nut 2|, is a ring 21. With the rod 8 in lowered position, the annular handle 9 and the ring 2'! are adapted to receive a suitable lock 28 (see Fig. l) for preventing operation of the pump.

It is thought that the operation of the pump will be readily apparent from a consideration of the foregoing. Briefly, upward movement of the rod 8 with the piston IIl thereon draws liquid into the lower portion of the barrel I past the foot valve I5. 011 the down stroke of the piston I0 this liquid is trapped by the foot valve I5 and is forced upwardly through the descending piston I0. Of course, this operation is continued, the

liquid above the piston l0 being elevated and discharged through the spout 25 and the flexible extension 26. When the sleeve 2 is screwed into the barrel or other container the element 4 engages said barrel or other container and functions as a lock nut. By removing the nut 4 the sleeve 2 may be adjusted to any desired position on the barrel, [thus the pump may be expeditiously mounted in containers of diiferent depths. As hereinbefore stated, by inserting a suitable padlock through the annular handle 9 and the ring 21 unauthorized operation of the pump will be prevented.

It believed that the many advantages of a barrel pump constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A pump of the character described comprising a barrel adapted to be inserted in a container, a split, threaded sleeve mounted for sliding adjustment on the barrel and adapted to be screwed into the container for mounting the barrel in position therein, a nut threaded on the sleeve for clamping said sleeve in adjusted position on the barrel, said nut further being engageable with the container for locking the sleeve therein, a manually operable rod in the barrel, and a liquid actuating piston on said rod and operable in the barrel.
